Regulable output microinverter?

Hello everyone and thanks in advance,

I have a 54v 50ah solar battery that i use with a grid tie microinverter. It works well with my setup right now because i charge the battery during the day with solar panels and turn the microinverter on during the night.

My current setup is: 2kw of solar panels plugged into a grid tie inverter that powers my house during the day and injects the remanings into the grid

1kw of solar panels that charge my battery, and at night i turn on the microinverter plugged into the battery to use basically 0 power from the grid

While my setup works great, it has a problem, The microinverter maxes itself and creates arround 600W during the night. I am looking for a regulable output microinverter, because when i cook dinner at night with my induction stove i need those 600W but when i go to sleep i don't need to be injecting 400W all night (my house uses only 200W at night)

So what can I do? Impossible challenge or there is a way to regulate a microinverter's output?

Thank you all,
